I was standing in the backyard with the dog when what appeared to be a sphere of flame rose out of the neighbors yard. I lost it behind the trees, then saw a sphere shaped object coming towards me from the same area. It was round and nearly silent, and was maybe 100 ft in the air, so even though it was fairly dark I was able to get a decent look at it.

It had blinking lights on it, and would have looked like a high flying plane had I not seen it come from between the tree scape instead of over them, and paid enough attention to it so I could make out the round shape of it.

There was just the one craft, but was spotted in the same 5 minute time span as an extremely high flying plane (I thought it was a satellite at first, this thing was flying way over commercial altitudes) and a what looked to be a low flying fighter jet (noticed him because he was perpendicular to the typical flight path of this area and the shape of the plane body)
